Final answer:
The aggregate demand and aggregate supply graph represents the relationship between the price level and the quantity of goods and services demanded and supplied in an economy.
Step-by-step explanation:
The aggregate demand and aggregate supply graph represents the relationship between the price level and the quantity of goods and services demanded and supplied in an economy.
At the intersection of the aggregate supply and aggregate demand curves, the graph shows the equilibrium level of real GDP and the equilibrium price level in the economy.
As the price level rises, aggregate supply rises and aggregate demand falls until the equilibrium point is reached.
